Well it looks like we almost made a BIG mistake Rich. When I was working on my sled the other day I was looking at those button headed rivets and thinking how they don't sit flush like the stock self-piercing rivets do. And then I think, "ya know, my chaincase is supposed to mount right over the top of those....ah shit...."

But luckily some pencil pusher at Polaris either strategically placed those rivets or merely be accident the chaincase lines up where it doesn't hit any of them. Tragedy averted.
